FILTER.

SPECIFICATION forming' part of Letters Patent N 0.735,835, dated August 11, 1903.

Application iiled June 8. 1903.

.To @ZZ whom, t Ina/y concern:

Be it known that I, LnwIs BAILEY SKIN- NER, a citizen of the United States, residing at Colorado Springs, in the county of El Paso and State of Colorado, have invented certain new and useful Improvements in Filters, of which the following is a specification.

My invention relates to filters, and more especially to filters used in chlorinating processes; and it consists in providing a foundation and in forming the ltering-bed in part of certain anged and perforated bars and in securing the latter asffully set forth hereinafter and as illustrated in the accompanying drawings, in which-'- Figure lis a longitudinal section of a chlorinating-barrel, showing my improvement. Fig. 2 is a transverse section; Fig. 3, a transverse section of one of the filter-bars; Fig. 4, a transverse section showing a filter-bar with two flanges and illustrating a different bolt connection from that shown in Fig. 2.

The construction of the casingAwill depend upon the purpose for which the filter is to be employed, but, as shown, it represents a barrel of a chlorinating-lter with the usual lead lining, if desired, and with end trunnions 1 and a filtering-bed O, constituted by what I term filter-bars B. Each of these bars consists of a body portion or web 2 and a flange 3 at the top of the body or web, extending laterally the length thereof and having perforations 4, which preferably increase in diameter toward the lower ends.

As shown in Figs. 1 and 4, the Iianges 3 project from the webs 2 at both sides; but they may project from only one side, as in Fig. 3. When they project from one side, the end of the flange is preferably beveled to form an inclined face-7, which can bear upon an inclined face 8 of the adjacent bar, thereby securing a rigid support. A .further support maybe securedY by means of laterally-projecting wings or brackets 9, ex-

tending from the web to the under side of the ange. When the bars extend transversely to the rounded casing or barrel A, it isv desirable to support them at intermediate points, and for this purpose I prefer to use posts 10, extending downward to the casing. As shown in Fig. 2, these posts are recessed and threaded to receive the threaded ends of Serial No. 16 0,624. (No model.)

bolts 12, extending through the casing, or, as shown in Fig. 4, the head of the bolt is embedded in the bar and the stem extends through the post 10'and through the casing other fastening device.

The bars may consist of any suitable material, but in chlorinating-barrels must be of someacid-resisting material, as lead, in which case the posts 10 are also of lead and the bolts 12 serve to strengthen the same. In this case also the casing or barrel is lined with lead 13.

Any suitable means may be employed for clamping the parts of the filtering-bed to the foundation, and torfurther brace/the filter cross-beams 15, extending between side bars 16, are held in place by wedges 17 driven bei tween the bars 16 and space-blocks'20. The space-blocks are held in place by end wedges 2l, and wedges 22 are driven between the space-blocks and the bars B, which are thus firmly held inplace. If desired, they may be burned to the'usual lining of the barrel.

tion set forth, I claimv 1. A filter-,bar consisting of a body portion or web with a laterally-projecting perforated ange at the top,fsubst'antially as described.

2. A filter-barconsisting of a body portion 0r web with a laterally-projecting perforated flange extending from one side at the top, substantially as set forth.

3. A filter-bar consisting of a body portion or web with a laterally-projecting perforated body having a beveled face at the side opposite the liange, substantially as set forth.

4. A filter-bar consisting of a body portion or web with a laterally-projecting perforated liange at the top, and webs or brackets extending between the flange and body, substantially as set forth.

5. The combination with a casing A, offilter-bars B each havinga body portion or web and a perforated side iiange, substantially as set forth.

6. The combination with a casing Aof filter-bars B each having a body portion or'web and a perforated side flange extending to and resting on the body of the next bar, substantially as set forth.

and is secured at the outer end by a nut or ange, the end of the liange beveled and the Without limiting myself to the construc- IOO 7. The combination in a filter with the casing A, of anged bars B, arranged side by side, supporting-posts, and bolt-s extending into said posts and through the casing, Snbstantially as set forth.

8. The combination with the filter-casing A, of anged bars B arranged side by side with the flanges in contact, supporting-posts, and bolts havingheads embedded in the bars extending through the posts and casing and secured thereto, substantially as set forth.

9. A filter-bar consisting of a body portion or Web with a laterallyprojecting perforated flange at the top and with lateral Wings 9, substantially as set forth.

l0. Alter-bed consistingof separa ted bars arranged side by side and having side flanges perforated, substantially as described.
